Upper panel: accretion rate onto the star versus time in the time interval t = [0.149, 0.150] Myr after the disk formation. Lower rows of panels: two-dimensional distributions of the ionization fraction (first row), turbulent parameter α (second row), and gas temperature (third row) in the region r ≤ 30 au at time instants t = 0.1491, 0.1493 and 0.1497 Myr marked with blue rounds with labels “A”, “B” and “C” in the upper panel, respectively. The white contour delineates the boundary of the dead zone.
